MapMart/IntraSearch and Harris Corporation offer high quality 1 meter DSM and 5 meter DTM data using stereo imagery from the 0.5 M resolution WorldView-1 satellite. WorldView-1 Imagery features a high capacity, panchromatic imaging system at a half-meter resolution. Operating at an altitude of 496 kilometers WorldView1 has an average revisit time of 1.7 days and is capable of collecting up to 290,000 square miles per day of half-meter imagery. From existing or newly tasked stereo imagery, the highly accurate and detailed elevation data will be created for any area specified.
The quality, resolution, and accuracy of this DEM product enables enhanced feature identification and exploitation, and provide a well established foundation for three-dimensional modeling of areas of interest (AOI). High-resolution DEMs have the level of detail needed to identify roadways, rivers, buildings, and other features.
The automated DEM production process outputs both Digital Surface Models (DSM) and Digital Terrain Models (DTM), also known as Bare Earth Models.
